PURPOSE:To provide an air conditioner drain valve in which passage of drain water is allowed but a reverse flow of odor is prevented. CONSTITUTION:An operation chamber 17 is constructed with a casing, which chamber elevatably accomodates a spherical valve body 18 having smaller specific gravity than that of water. A flow outlet 20 having a valve seat 19 on which a valve body 18 is seated is provided on a bottom of the operation chamber 17. A lower end of an upper drain tube 12 provided extending from a drain of an air conditioner is connected with a flow inlet 21 provided at the upper part of the actuation chamber 17, and an upper end of a lower drain tube 14 opened toward a drain pit is connected with the flow outlet 20. Hereby, the valve body 18 is ordinarily held on the valve seat 19 with use of self weight to prevent odor from reversely flowing when drain water flat into the actuation chamber 17, the valve body 18 is floated with buoyancy by the drain water to open the flow outlet 120. |
